Jelly Bean available to Vodafone and Three Galaxy S3 users

Samsung Galaxy S3 users on Vodafone can now (or at least very soon) upgrade to Android 4.1 Jelly Bean.

The update started rolling out today but "will be a staggered release, meaning customers will be notified in batches that it's available for over the air download over the course of several days," according to a Vodafone company blog post.

The network also advised using Wi-Fi to download Jelly Bean over the air, since the file is relatively large.

However, Vodafone also stated, "if you'd like to update without waiting for the over the air prompt, connect your phone to your PC with Samsung Kies and you'll be able to update once it's available on Monday."

Last Thursday, Three took to Twitter to announce the availability of the Jelly Bean operating system to its network's Galaxy S3 users, linking out to a Three UK support page with instructions on how to proceed.

Jelly Bean contains numerous visual and performance-based improvements upon its predecessor, Ice Cream Sandwich.

Google is expected to announce a new version of its mobile operating system at an Android event next week, where the tech giant is also expected to unveil two new Neuxs devices - a smartphone and a high-end tablet.
